The outer faces of said lugs 25, particularly at the tops thereof, are preferably fiat, as shown in Fig. at, to engage with interlocking means provided on the tap-plate 26, which will be hereinafter more fully described.

Said tapped members or nuts 27 may be made of any suitable shape and are preferably of the flat-faced and outwardly.taperedtype, as shown in the drawing,.which, as may be understood, when embedded within the cast ing, will stay set against turningor moving from their set positions therein. 30 represents a section of the heel mould which shows schematically the means ofsupporting the tapped members or nuts 27 .in position within said mould to become embedded within the heel lug which is to be formed in the space 31 therein shown, 32 represents the supporting screw on which the tapped r member 27 is; received andheld set within the m ould,.and which screwis itself held in the mould as shown. It willbe here noted that by supporting the nut 27 in the aforesaid manner, namely, on a screw threadedly fitting within the same (as 32 which has the threads extendingon either side of the position of the nut 27), the metal poured into the mould30 will fill the space 31 and settle .aroundvthelnut. 27 ,and the screw 32,

I whereby the nut 27 becomes embedded in the casting and the screw 32, which supports the nut 27 and projects into. the space 31, will form a thread in the casting on either side of the nut so 'thatwhen the mould screw 32 is ultimately unscrewed and removedfrom the heel casting, a tapped hole 33 on eitherside of the nut 27 will be formed, as shown in Fig. 8,. which registers with the tapped hole of the nut 27 and is expo'sedto the top of theheel, as shown in Fig. 4.

which securely couples the heel socket piece 38which is preferably made of leather and tofwhich the tread lift 39 may be. secured by ,suitablemeans, as the, clencher brads AC0 (F1g. 6). Said coupling screw 37 may be employed to support the tread lift direct,

as indicated in Fig. 2, where the lift shown is a rubber heel shaped to fit within the heel socket 22, with the tread section of the lift made integral with the socket insert section.

The tap-plate 26, which preferably made horseshoe-shaped, as indicated in Figs. 1, 3 and 5, may be made of any suitable material, as for example, steel, and may be so designed as to be stamped out of sheet stock; or if preferred, may be die cast. In either case, the characteristics which are necessary to attend the same for functioning, as is herein required, may be provided to equal advantage.

Inthe drawing, I have represented the tap-plate 26 as a casting plate, wherein 41 ,represent the downwardly projecting lugs which form a socket for receiving the tops oft-he heel lugs25, as shown in Figs. 1, 2, 6 and 7. Said tap-plate 26 is preferably conc-aved slightly to fit within the heel member .20 and to rest on the lugs 25 thereof, as shown in (5, with the outer edge of said plate26 preferably setting just inside of the outer edge of the top of the heel member 20. Further, said plate is provided with the anchor or coupling screw holes 42. which are positioned to register with the holes 33 of theheel member 20, and the clencher nail holes 4C3 which accommodate the clencher nails or brads 44, as shown, and by means of which the tap-plate 26 is securely attached to the shoe bottom S.

Having thus described the parts of my invention in detail, the manner in which the same may be employed is as follows:

First, it will be observed that the employ-- ment of the tapped member or nut in the the use of the ordinary light-weight aluminum in the construction of the heel member, \VlllCllzlS desirable, but supplies the same with a reinforced anchoring medium which overcomes the disadvantages and trouble encountered when relying upon threads cut in. the relatively soft aluminum stock for providing tapped holeswith which to engagethe screw types of anchoring or coupling elements. Said tapped. members 27, as may be understood. may be made of different, and a relatively harder, metal. than Similarly the tapped memberor nut 35 the heel member, and if desired, may be hardened or treated to stand up in the heel against any ordinary strain directed thereagainst, whereby the heel not only becomes a much safer element than is otherwise postill lit

"oil

late

lrleoond, it will be observed that the heel member, as herein disclosed, with the embedded nut feature, may be as-isociated directly with the shoe without the absolute necessity for the en'iployment of the tapplate shown and. described herein; it being finally, it serves as a brace for the heel member and the shoe as well as a firm. support for the shoe setting; thereon. These latter functions warrant the use of said tap-plate in connection with the heel, and this combined use, as herein disclosed, assures comfort and safety to the wearer besides adding" life to both the shoe and the heel.

The tap-plate 26 is properly positioned on the shoe bottom bi, as is shown in liig. 5, and zlll'lKQCl thereto through the medium of the brads or clencher nails ll which set in the plate holes d3 provided therefor. With the tap-plate thus ail-lined to the shoe, holes registering with the tap-plate holes at) are provided in the shoe bottom to re ceive the coupling screws The shoe is thus made ready to receive the heel member 20, which is set to include the trap-plate therein, as shown in Fig. l, with the top edge of the heel. adjacent to the shoe and the lugs registering with the sockets provided in the tap-plate and formed from the lugs d1. 'llhe coupling or ancl'roring" screws 28 are then inserted through the holes provided therefor in the shoe bottom and the holes 42 of the tap-plate to engage with the tapped holes 33 of the heel member; said screws 28 being preferably of sufficient lengths to assure of engagon'ientwith the tapped members 21 which are embedded in the heel member for the purpose of engaging said screws to provide an absolutely reinforced and reliable holding means therebetween for coping with the strains and stresses set up there-against and without which reinforcement the aluminum heel cannot possibly be depended upon, especially when relying wholly upon the engagement of said screws with aluminum threads cut in the heel itself. It will thus be understood that the screws 28 may be screwed in tight into the heel member and without danger of strippii ig the threads in the latter. 'lhat feature will permit of absolute take-up to solidly andrigidly anchor the heel to the shoe, and in that manner overcomes the disadvantages attending the use of the ordinary typesof aluminum heels which have been faulty, unreliable, and unsafe because of the relatively delicate and weal; anchor ing means provided the same. lhe tapplate is simple and inexpensive to manufacture, and the introduction of the embedded tapped members in the heel, as well as the plOv'iSltil'l of the lugs for receiving the same, adds very little expense to the cost of manufacture of the heel member over the ordinary types in use. The work of. attaching the tap-plate and heel member with the shoe is simple and requires no great degree of skill on the part of the operator, and the result of its use necessarily assures of a neat and lasting ob, possessing the safety feature which is obviously most desirable.

Similarly, the application of the tapped member or nut in the bottom of the heel, which is employed for engaging with the coupling screw which couples the tread lift of the heel with the heel member, possesses advantages which are obviously most desirable, especially when the heel is made of aluminum, in which event it allows for a screw take-up between the coupling screw and the heel member for securely engaging the tread lifts with the heel member.

ft is a known fact in the manufacture of aluminum heels that the finely gauged threads of the tapped holes provided therein, are entirely too susceptible to becoming stripped to render the same practical. "Wherefore my invention is directed to remedy such consequences.

While the preferred embodiments of my invention have been described in detail, it will be understood that I do not wish to be limited to the particular construction set forth, since various changes in the form, material, proportions, and in the details of construction may be resorted. to without departing from the spirit and scope of the invention, or destroying any of the advantages contained in the same, heretofore described and defined in the subjoined claims.
